Ok so in my limited FP experience heres what i came up with so far that doesnt require an air knight or a side square to up square.
Short Jump down square-right circle-short jump down square-neutral square square-up square-jump right triangle.
145
.....
I...ill keep looking.
Edit: its easier than right square up square tho so you have that at least.
Thanks! The added short hop down square feels slightly awkward for me, since i'm not used to doing short hops in the middle of combos with any character, but i can definitely work with this. I just tried it out a few times in practice mode and it's very doable for me. With a little bit of practice it should become second nature. In any case it's vastly preferable to the incredibly inconsistent side square, up square.
I think i just found out what the problem with the latter is. Too strong knockback for side square in combination with the hitbox being too small (relatively to the knockback) for most characters. I just tried it with about 10 different characters and the only one where i had a 10/10 success rate is Big Daddy. Everyone else is more like 2-3/10 for me (unless i'm close to a wall, then it's 10/10 against anyone), if that. That's way too low to rely on it in the heat of battle. How about fixing this in a future patch, SSM? Obviously i'm not asking for an increased hitbox for 23 characters, but a decreased knockback for FP's side square would do, i think. Also, bring back the fast air knight and just add a short cooldown before you can use it again, that should curb spamming, while keeping the move useful against human opponents.
Anyway, thanks again, this will alleviate my FP combo worries a good deal. It's still a huge bummer though that so many interesting combos for her got gimped with this patch, just when i was set on getting better with her. I'm looking forward to any other combo suggestions when you have the time.
Edit:
Oh wow, i've just made a 155 combo with FP by accident. That's a new record for me. I started out with the air knight though, so i don't know how much use it will get online. Instead of the ground knight i accidentally summoned a fire mage, the rest of the combo was the same. Now to see if i can replicate it or if it was a fluke. Timing the fire right might be a bit difficult since the knockback from it could interfere with the rest of the combo.
Edit2:
Bah, total fluke, can't come close to replicating it again. Maybe someone else will have more luck. :l
Edit3:
No, wait. I can actually pull it off 50% of the time now, but the spacing when summoning the fire mage has to be exactly right. This only works with the air knight combo starter though, as you need to follow it up with a (charge) square to have enough time to summon the fire mage. Oh man, that makes me even more salty about the air knight nerf.
